LabCompanion P-Series Programmable Temperature and Humidity Environmental Test Chamber

Overview

The LabCompanion P-Series Programmable Temperature and Humidity Environmental Test Chamber is an engineered solution for accelerated environmental stress testing of materials, components, and finished products under precisely controlled thermal and hygrometric conditions. Based on the principle of forced-air convection with dual independent control loops—PID-regulated refrigeration, heating, and humidification subsystems—the chamber delivers stable, repeatable, and traceable test environments compliant with international standards for reliability validation. Designed for laboratory and industrial QA/QC applications, it supports steady-state and dynamic cycling protocols across wide operational ranges: from −70 °C to +150 °C and 30–98% RH. Its architecture integrates thermodynamic isolation (high-efficiency polyurethane or fiberglass insulation), corrosion-resistant 304 stainless steel interior, and a vacuum double-glazed observation window with anti-frost coating—ensuring long-term dimensional stability, minimal thermal leakage, and unobstructed visual monitoring.

Key Features

• Advanced bilingual (English/Chinese) 7-inch LCD touchscreen controller with intuitive menu navigation, real-time curve visualization, and full program editing capability—including 120 user-defined programs, each supporting up to 1200 segments and 999 loop repetitions.
• High-precision control system featuring 9 independent PID parameter sets per channel (temperature/humidity), enabling fine-tuned adaptation to diverse load masses and thermal inertia profiles.
• Dual-mode cooling architecture: air-cooled standard configuration (RP/LP/SP series); optional water-cooled variants (LP/SP models) for high-heat-load or ambient-temperature-constrained installations.
• Uniform airflow design with rear-mounted centrifugal blower and optimized baffle layout ensures temperature deviation ≤±2 °C and humidity uniformity within ±2% RH (≤75% RH) or ±3% RH (>75% RH) across the working volume.
• Integrated safety and diagnostics: comprehensive fault detection (compressor overload, heater open-circuit, humidity sensor drift, water shortage), on-screen alarm codes, and automatic shutdown with event logging.
• Front-access auto-fill humidification system with stainless-steel sheathed surface-evaporation heater; low-maintenance design with visible water level indicator and quick-release drain valve.
• Standard 50 mm diameter test port with sealed cover, two adjustable stainless steel shelves, four shelf supports, and internal fluorescent lighting—all conforming to ISO/IEC 17025-compliant calibration accessibility requirements.

Sample Compatibility & Compliance

The P-Series accommodates a broad spectrum of test specimens—from printed circuit boards (PCBs), semiconductor packages, and polymer enclosures to aerospace fasteners and automotive ECUs—without compromising environmental fidelity. Its internal dimensions (150–800 L options) support both single-unit validation and batch-level qualification. All models are designed and verified to meet stringent regulatory and industry-specific test standards, including: GB/T 2423.1–4 (cold, dry heat, damp heat, cyclic damp heat), IEC 60068-2-1 (cold), -2-2 (dry heat), -2-3 (damp heat, steady-state), MIL-STD-810F Methods 501.4 (high temperature), 502.4 (low temperature), and 507.4 (humidity), JESD22-A101-B (constant temp/humidity), A103-C (high-temp storage), A119 (low-temp storage), and GJB 150.9 (military damp heat). Optional RS485 interface enables integration into GLP/GMP audit trails when paired with validated data acquisition software.

Software & Data Management

The embedded controller logs all operational parameters—including setpoints, actual chamber values, alarm timestamps, and program execution status—at user-configurable intervals (1–600 seconds). Data export is supported via USB memory stick or RS232/RS485 serial link to external PCs. When connected to LabCompanion’s optional Environmental Test Suite (ETS) software, users gain access to automated report generation (PDF/CSV), multi-chamber synchronization, electronic signature workflows, and 21 CFR Part 11-compliant audit trail functionality—including user authentication, change history, and immutable record retention. Calibration certificates for temperature and humidity sensors (traceable to NIM or NIST-equivalent national standards) are provided upon delivery and may be re-verified in situ using optional PT100 reference probes.

Applications

This chamber serves critical roles in product development lifecycle stages: early-stage material compatibility screening (e.g., adhesive curing behavior under humid aging), mid-cycle reliability assessment (e.g., solder joint fatigue under thermal-hygroscopic cycling), and final certification testing prior to market release. Typical use cases include: accelerated life testing of lithium-ion battery modules under combined thermal and moisture stress; validation of IP-rated enclosures against ingress-related degradation; qualification of optical coatings for aerospace instrumentation; verification of medical device packaging integrity per ISO 11607; and compliance testing of automotive electronics per AEC-Q200. Its reproducible performance makes it suitable for inter-laboratory comparison studies and accredited third-party certification labs.

FAQ

What is the standard warranty period for the P-Series chamber?
LabCompanion provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship, excluding consumables (e.g., humidifier tanks, filters) and damage resulting from improper operation or unauthorized modification.
Can the chamber be calibrated to ISO/IEC 17025 requirements?
Yes—calibration services with accredited documentation (including uncertainty budgets and traceability statements) are available through LabCompanion’s authorized metrology partners; on-site calibration kits with certified reference sensors can also be supplied.
Is remote monitoring possible without installing additional hardware?
Basic remote status viewing and manual setpoint adjustment are supported via RS232-to-Ethernet gateway; full supervisory control requires ETS software and optional Ethernet module (not included in base configuration).
How does the chamber handle condensation during rapid cooldown?
The system employs pre-cooling dehumidification and controlled ramp-down algorithms to minimize internal condensation; the stainless steel interior and insulated door gasket further reduce dew-point-related surface moisture accumulation.
Are custom internal configurations (e.g., extra ports, specialized shelving) available?
Yes—LabCompanion offers OEM engineering support for non-standard modifications, subject to structural integrity review and thermal modeling validation. Lead time and cost implications are assessed case-by-case.
